Burn More Calories With the Perfect Playlist

Whether you're running, biking or elliptical-ing, you need to ease into cardio to prime muscles. So pick two songs at about 120 BPM. That's short for beats per minute and roughly correlates to what you want your heart rate to be. Athletes were able to bike faster after warming up to music between 120 and 140 BPM, an Asian Journal of Sports Medicine study reports.
